Waterproofing Polyurea kitsfor roofs
ETAG 005 “Liquid applied waterproofing kits“ – For polyurea part 6, „Specific stipulations for kits based on polyurethane“ mostly is applicated► Requirements concerning performance according to Essential Requirements
(ER CPD), e. g. mechanical resistance and stability, reaction to fire, emission ofdangerous substances, durability, safety in use.
► Categorisation according to use (examples): Categorisation according to working life;
Categorisation accorrding to climatic zone in use
Categorisation according to user loads (like pedestriantraffic, traffic or plants)
Categorisation according to surface temperature;
Examples for application areas1: Flat roof, 2. balconies 3. terraces4. extensive and intensive greening5 Details,

Chronologic development of liquid applied waterproofing kits in German regulation
1997 Liquid applied roof waterproofing kits were firstly listed in German DIBt “Construction products list” (BRL),
2001
• Publication of ETAG 005• Integration of liquid applied roof waterproofing kits (PUR, MMA, UP)• Revision of “Flachdachrichtlinie” (flat roof guideline) of ZVDH (central association
of roofers) with relation to liquid applied reactive resins
2003 Expansion in German “Construction products list (BRL) with applications for balconies, terraces and green roofs
2004 Integration of waterproofing with liquid applied reactive resins into BRL
2008 New edition of “flat roof guideline” of ZDVH
2009
• International IFD-guideline for planning and execution of roofs and waterproofing of roofs (flat roof guideline)
• Integration of waterproofing liquid applied water proofing products in DIN 18195 (German general standard for application of waterproofing products).
2010 Publication of DIN 18531 (German standard for waterproofing of roofs)

PDA Europe 2011 Annual Conference – The Hague, 14-17 November Hohberg
Integration of polyurea products in German roof waterproofing regulation
In Germany application of liquid applied waterproofingkits is ruled► For unused roofs (non-accessible; extensive vegetation) in:
DIN 18531 „Waterproofing of roofs“, part 1 to 4
ZVDH (central association of roofers) „Technical guidelinefor waterproofing = flat roof guideline“
► For used roofs (accessible or intensive vegetation; balconies, terraces...) in- in ZDVH „flat roof guideline“
In Germany for the time being polyurea is not integrated in DIN 18531, therefore is not integrated in „flat roof guideline“ of ZDVH

Open questions/topics: ► Complete list of references for polyurea products (with objects older
than 5 years) necessary► Control/measurement of layer thickness; ► Convincing of (traditional) roofers concerning the safe application of
polyurea

CEN published about 250 hEN

Essential requirements of the Construction ProductsDirective (CPD)1. Mechanical resistance and
stability2. Fire safety3. Hygiene, health and
the environment4. Safety in use 5. Protection against noise6. Energy economy and heat
retention
The construction work must be designed and built in such a way that it will not be a threat to the hygiene or health of the occupants or neighbours

Emission into Indoor Air –ongoing activities
► Test chamber method (EN ISO 16000 – 9) is suited to assess release of VOC/SVOC from construction products
► Target of CEN/TC 351/WG2: improve reproducibility and soundnessof the test method harmonize and limit test parameter
(volume, air exchange rate, loading factor)
► Robustness validation is organised. Results expected 2012. (same timetable as indoor air)
► 2. validation phase (round robin): financing still open
► Open question:Communication of test results in the CE-mark

Amendment of mandatesconcerning regulated DS
EC-EGDS: Ongoing amendment of construction products mandates:► In the progress of the implementation of the CPD
the EC issued mandates to CEN.► On the base of these mandates the product-TCs elaborated
European harmonised product standards.► EGDS now is active to add the aspects of health, hygiene and
environment (ER3-aspects) into the CP-mandates.► As a rule: Only if notified regulations concerning ER3 exist in
the EU-MS, the relevant product standard/mandate will be amended to resolve barriers to trade.
22
PDA Europe 2011 Annual Conference – The Hague, 14-17 November Hohberg
Amendment of EC mandates concerning dangerous substances
Status of revision of mandates:► 3 of 30 revisions of mandates have been presented to SCC, adopted and
given to CEN: M/103 “Thermal Insulation“; M/104 M/119 “Floorings“ (EN 13813, resin screeds) M/125 “Aggregates“
► 12 of 30 mandates are presently under internal discussion by COM-EGDS (final check EGDS June 2011) and were presented to SCC: M/101 “Doors, Windows and related Products”, M/106 “Gypsum”,
M/108 “Curtain walling”, M/111 “Circulation fixtures”, M/112 Structural timber products and ancillaries; M/115 “Reinforcing steel”, M/116 “Masonry and related products”, M/121 “Internal and external wall and ceiling finishes”, M/122 “Roof coverings”; M/124 “Road construction products”; M/135 “Glass”
While MS reacted in favour of the mandates, CEN/TCs have concerns
23
PDA Europe 2011 Annual Conference – The Hague, 14-17 November Hohberg
European approvals – EOTA –EOTA-PT9 “Dangerous Substances“
► Products (Systems) too innovative or too complex to get standardized, can achieve an European technical approval (ETA), e.g. according to ETAG 005.
► EOTA-PT9 discusses how aspects of environment and health have to be considered in ETAs.
► Relevance of EOTA-Product goups (ETAGs) in relation to the different emission scenarios have partly been laid down.
► Check lists with dangerous substances and assessments classes have been elaborated.
► But: as long as TC 351 is not ready, test and assessment procedures are missing – therefore for the time being national methods are applicated.

PDA Europe 2011 Annual Conference – The Hague, 14-17 November Hohberg
Summary
CPD and the new CPR require information on environmental information. This information shall be integrated in CE-Mark
CEN and EOTA are preparing rules and/or test methods to address release into indoor air and soil, surface and groundwater
Members of CEN product TC‘s shall be aware of themandate expansions
Manufacturers/associations should be prepared to draft dossiers on environmental data
